Abstract:There is a popular conception that the best plants for controlled experimentation, particularly for molecular biology, should be produced in a growth chamber under highly controlled conditions. Daylight levels and temperature variation in the field have a much greater range than that normally reproduced in controlled environments. Both light and humidity have been demonstrated to affect expression of defence-related genes, including those involved in the production of reactive oxygen species (ROS). Climate change can affect the defence against pathogens and parameters such as increased ozone or carbon dioxide concentration and drought have been shown to upregulate the expression of many specific defence-related genes as well as oxidative stress-related, ethylene-related, jasmonic acid signalling-related and defence flavonoid-related genes. Several fungicide active ingredients, such as proquinazid and some strobilurins, are thought to possess resistance induction properties.
